DATA LOGGER
The built-in data logger is capable of utilizing SD 
(2GB maximum) and SDHC (4GB maximum) 
memory cards. 
The sampling rate for the data logger may be set to 
record readings from every 1 minute to every 720 
minutes in 1 minute increments. A 1 minute interval 
will record 1440 readings/day. A 720 minute interval 
will record 2 readings/day. 
SD CARD SELECTION
The supplied 256MB SD memory card is ready for 
immediate use. When utilizing 3rd party SD/SDHC 
cards, insure that they are formatted as FAT16 or 
FAT32, NTFS format is not supported. SD cards up 
to 2GB and SDHC cards up to 4GB are supported. 
Cards over 4GB and MMC/SDXC cards are not 
supported. 
The supplied 256MB SD card is capable of storing 
5.9 million readings (over 10 years of readings at 1 
minute intervals).
Higher capacity memory cards require more power 
to operate; therefore, larger cards will exhaust the 
batteries more rapidly (see the “AC Power Supply/
Battery Power” section).
INSERTING/REMOVING SD MEMORY CARD

3. Open the SD card door by lifting up on the bottom
 of the door.
4. Push the SD memory card until it “clicks”, then
 release to allow the card to be ejected.
To insert the SD memory card:
1. Turn the meter off, by pressing the ON/OFF
 button.
2. Open the SD card door by lifting up on the bottom
 of the door.
3. Make certain that the SD memory card is oriented
 properly (see image) and insert by pushing the
 card until it “clicks”.
4. Close the SD card door by snapping it shut.
5. Turn the meter on by pressing the ON/OFF button.
6. Turn data logging on, if desired (see the “Turning
 On/Off Data Logging” section).
ADJUSTING DATA LOGGER RECORDING RATE
The sampling rate for the data logger may be set to 
record readings from every 1 minute to every 720 
minutes in 1 minute increments. A 1 minute interval 
will record 1440 readings/day. A 720 minute interval 
will record 2 readings/day. 
1. Press and hold the SET button for 3 seconds,
 
release the SET button when “SET” appears at
the bottom right side of the display in place of the
clock.
2. The low alarm limit for the ambient temperature
 will appear.
3. Press the SET button six (6) times to pass through
 the alarm set-points, 
rAtE should appear on the
display.
4. The number  ashing is the data logger recording
 interval (expressed in minutes). Press the  or
  button to increment the display to the desired
 value.
5. With the desired value on the display, press the
 
SET button to return to the current temperature/
humidity display.
TURNING ON/OFF DATA LOGGING
Prior to starting data logging:
 Make certain that the time-of-day and date have
 been set properly (see the “Setting Time-of-Day/
 Date” section). The recorded data will be time/
 date stamped using the time-of-day/date setting. 
 Make certain that an SD/SDHC memory card is
 inserted into the meter (see the “Inserting/
 Removing SD Memory Card” section).
 Set the desired °F/°C display mode (see the
 “Displaying °F or °C” section).
 Set the desired data logger recording rate (see
 the “Adjusting Data Logger Recording Rate”
 section).
To toggle data logging On/Off, press and hold 
the SET button for 6 seconds (each time this is 
performed, it will toggle from on/off and from off/on):
OFf rEc indicates that the data logging function is off.
ON rEc indicates that the data logging function is on. 
While data logging is occurring, the clock section will 
alternate between displaying the time and 
rEc.
If the meter is turned off, the data logging will 
also be turned off. When the meter is turned on, 
data logging must be turned back on by using 
the above procedure.
If the SD card is removed while data logging is 
turned on, 
Err and Sd will alternate on the display
in place of the clock to indicate that the meter is no 
longer recording data. Insert the SD card to return to 
data logging.
The following will cause data logging to stop/
turn off:
• Turning the meter off
• Low battery power (
), when using batteries only
• Power failure, when using the AC power supply only
• Removing the SD memory card
• Changing the time-of-day/date
• Changing the data logger recording rate
• Changing the High/Low alarm settings
• Changing display from °F/°C, °C/°F
• Pressing the RESET button
Once data logging has been stopped, it must be 
turned back on.
DATA LOGGING FILE FORMAT/STRUCTURE
With data logging turned on (see the “Turning On/Off 
Data Logging” section), the meter will write a  le to 
the SD memory card. The  le created is a standard 
text (.TXT)  le. 
Once data logging has started, the  lename created 
is based on the start date (month and day number) 
and time. 
Example: Start 11/28/2013 at 16:48, will create a  le 
with the name “11281648.TXT”.
The maximum size per  le is 30,000 records. During 
continuous data logging, once the maximum  le 
size has been reached, a new  le is automatically 
created utilizing the same  le naming method. A 
 le containing 30,000 records represents over 20 
days of minute by minute data. Depending on the 
selected data logger recording rate and the duration, 
continuous data logging may generate numerous 
 les containing data.
The  le created is a  xed width data  le that may 
be read utilizing any computer application capable 
of reading “.TXT”  les (Word®, Excel®, NotePad, 
WordPad, etc).
The text  le is structured as follows:
Header 
Column Position

................................... 1-10

(HH:MM:SS)
...................................... 12-20

This will show either F or C depending on the value that
was selected to be displayed on the meter when data 
logging was started.
READING THE DATA FILE(S) FROM THE SD 
CARD
1. Remove the SD memory card from the meter 
 (see the “Inserting/Removing SD Memory Card”
 section).
2. Insert the SD memory card into the supplied USB
 SD card reader. (If the computer being used has
 a built-in SD card reader, the USB card reader is
 not required.)
3. Plug the USB SD card reader into an available
 USB port on the computer. The  rst time the USB
 card reader is plugged in to the computer, drivers
 will automatically be installed to allow the card
 reader to function.
4. Browse to the SD card and select the  le(s) 
 to view. 
5. Open the  le(s) in the desired program (Word®,
 Excel®, NotePad, WordPad, etc).
To open from Excel®, example:

PLACEMENT/MOUNTING OPTIONS
Bench Stand - The meter is supplied with a bench 
stand that is a part of the back of the meter. To 
use the bench stand, locate the small opening at 
the corners on the back of the meter. Place your 
 ngernail into the opening and  ip the stand out. To 
close the stand, simply snap it shut.
Wall Mount - Set a screw into the wall at the location 
desired. The head of the screw will need to slip 
into the receptacle on the back of the meter, do not 
set the screw  ush to the wall. Once the screw has 
been set properly, hang the meter in place by sliding 
the receptacle on the back of the meter over the 
head of the screw. 
Magnet - A magnet is supplied with the meter. Peel 
the protective paper off the adhesive tape on the 
magnet. Press the magnet onto the back of the 
thermometer and mount on any metal surface.
Hook & Loop - Self adhesive hook and loop 
mounting tape is supplied with the meter. Peel off the 
protective backing. Adhere one piece to the meter 
and the other to any clean,  at surface.
ALL OPERATION DIFFICULTIES
If this meter does not function properly for any 
reason, replace the batteries with new, high-quality 
alkaline batteries (see the “Battery Replacement” 
section). Low battery power can occasionally cause 
an number of “apparent” operational dif culties. 
Replacing the batteries with new fresh batteries will 
solve most dif culties.
ERROR CODES
E02 
Indicates that the value being measured is
below the measurement range of the meter
(too low).
E03
Indicates that the value being measured is
above the measurement range of the
meter (too high).
E04
Indicates that the temperature sensor has
been damaged.
E11
Indicates that the humidity sensor has
been damaged.
E32/E33 Indicates that the meter has been damaged.
BATTERY REPLACEMENT
An erratic display, faint display, no display, or 
appearing on the display are all indicators that the 
batteries need replacement.
If the AC power supply is not being used when the 
batteries are being replaced, the meter will turn off 
once the batteries have been removed. The meter 
and data logging will need to be turned back on once 
the batteries have been replaced.
If the AC power supply is being used when the 
batteries are being replaced, the meter will continue 
to function without interruption.
Remove the battery cover located on the back of the 
meter. Remove the exhausted batteries and replace 
them with three (3) new AA alkaline batteries. Make 
certain to insert the new batteries with the proper 
polarity as indicated by the illustration in the battery 
compartment. Replace the battery cover.
